Wouldn't a "gift to act morally" then be considered unnatural since we are the only ones to do it and, according to them, have to be taught to do so (after all, without the bible then we are obviously immoral *rolls eyes*)?

Atheist, as I ask Christians, those who practice homosexuality, it's your business what you do with your bodies and who you chose to do it with, keep it to yourself. You bring it in the public square and it should be treated just like any other belief system.
